Overview

This snippet demonstrates how to obtain the number of available sensors on your device (for example, two on the Nokia N95 8GB: accelerometer sensor and rotation sensor).

Note: In order to use the code, you need to install the sensor plugin for your SDK.

MMP file

The following libraries are required:

LIBRARY RRSensorApi.lib

Source file

#include <RRSensorApi.h>
RArray<TRRSensorInfo> sensorList;
CleanupClosePushL(sensorList);
 
// Retrieve list of available sensors
CRRSensorApi::FindSensorsL(sensorList);
 
// Get number of sensors available
TInt sensorCount = sensorList.Count();
 
CleanupStack::PopAndDestroy(); // sensorList

Postconditions

The number of available sensors is obtained.
